The Roland TR and CR emulation plugins by Marvin Pavilion are all excellent. The plugins can hold their own against commercial sample packs, as well as replicas as those by D16 group (which are also nice, if you have some money to spend).

This is the the one I was looking for. I downloaded it, try it out and the sounds are on the money!! The interface almost look like a real TR-808!! DOWNLOAD THIS MUTHA NOW!! TS-808 interface looks tame compare to this!
